How CMS usage is detected

Methodology

Company data

Detected companies are joined to UK Companies House records and XBRL accounts data. Revenue and headcount figures come from the most recent filed accounts; where the company has not filed, values are estimated using a model trained on filed history and peer benchmarks and are labelled as estimates.

Detection

Firmbase crawls the public website of actively-trading UK companies and fingerprints the technologies present: tracking scripts, embedded forms, chat widgets, CMS markers and similar signatures. A company is included in this list when one or more of the technology's signatures are found on its site; closely-related variants of the same product are grouped under one name. Detection covers what is visible on the public web — a company using the technology purely internally, with no website footprint, will not appear. Counts are therefore a conservative floor, not a ceiling.

Freshness

Websites are re-crawled on a rolling basis and the underlying company data is refreshed from Companies House continuously; filings appear within days of submission. The list and its statistics are regenerated when the detected cohort moves meaningfully. You can see the last-updated timestamp near the top of the page.

Frequently asked questions

What is the most-used CMS among UK B2B companies?
WordPress is the most-detected CMS among UK B2B companies, with 73.5% share (58,989 of 80,247 companies with a detectable system), ahead of Wix (9.5%) and Squarespace (5.4%).
How many UK B2B companies have a detectable CMS?
80,247 of 112,345 actively-trading UK B2B companies (71.4%) have a CMS detectable from their public website. The remainder either run systems with no public web footprint or none at all, so detected share figures are a conservative floor.
What is a CMS?
A CMS is the system used to create, edit and publish website content without rebuilding the site for every change. For UK B2B companies, it usually handles service pages, sector pages, news posts, downloadable content and contact forms. It gives non-technical teams a managed publishing layer while developers or agencies control templates and integrations.
How is CMS usage detected?
Firmbase crawls the public website of every actively-trading company in this scope and fingerprints the technologies present — scripts, widgets, booking and checkout flows. A company is attributed to a system when that system's signatures are found; systems with no public web footprint are not attributable, which is why every share figure on this page means share of companies with a detectable system.
Which has more UK B2B companies, WordPress or Wix?
WordPress: 58,989 detected companies versus 7,660 for Wix, of the 80,247 UK B2B companies with a detectable CMS.
What is the best CMS for UK B2B companies?
Best is not inferred from installation share; the ranking reports observed CMS usage rather than recommendations. WordPress has the largest share in all three employee bands: 73.2% of 53,980 companies under 10 employees, 73.7% of 23,368 companies with 10–50 employees, and 77.6% of 2,899 companies over 50 employees. Across companies with an identified CMS, WordPress accounts for 58,989 companies (73.5%), followed by Wix with 7,660 companies (9.5%), Squarespace with 4,355 companies (5.4%) and Webflow with 2,492 companies (3.1%).
